Currently `udiv i64 i32` compiles to a preudocode like: `if dividend > 32) < divisor) {
return (uint32_t)(dividend / (uint64_t)divisor);
} else {
__builtin_unreachable();
}…

## Summary
LLVM transformations of expressions with `BSR` (Bit Scan Reverse) instruction leads to redundant `XOR`s and `TEST` and prevents `LEA` arithmetics on x86 and x86-64.
## Details
If m…

I would love it if this library had methods analogous to xor from lodash (https://lodash.com/docs/4.17.15#xor).

When applied to a matrix, `bit:::xor.logical` drops matrix dimensions. Since `base::xor` (and `bit:::xor.default`) retain matrix dimensions, this means that the results of `xor()` calls can differ de…
